"Wheel gun" is a term commonly used in the context of Formula 1 grand prix racing to describe a handheld pneumatic tool that is used to tighten and loosen the wheel nuts on a racing car's wheels during pit stops.

The wheel gun, also known as a wheel nut gun or an impact wrench, is an essential tool used by pit crews during Formula 1 races. The tool is designed to provide a quick and efficient method of changing tires during pit stops, which can often be the difference between winning and losing a race.

The wheel gun works by using compressed air to turn a rotor inside the tool. As the rotor turns, it generates a high amount of torque, which is used to tighten or loosen the wheel nuts on the car's wheels. The tool is typically operated by a member of the pit crew, who attaches the tool to the wheel nut and then activates it to tighten or loosen the nut.

Wheel guns are highly specialized tools that are designed specifically for use in Formula 1 racing. They are typically made from lightweight materials such as aluminum or carbon fiber to reduce weight and increase speed. In addition, they are often customized to suit the specific needs of a particular team or driver, with different torque settings and other features to ensure that the tool is as effective as possible during pit stops.

In recent years, wheel guns have become a source of controversy in Formula 1, with some teams and drivers complaining that they are not always reliable or consistent. However, the wheel gun remains an essential tool for any Formula 1 team looking to achieve success in this highly competitive and challenging sport.
